1A- 5-17144/1+2/+ The present invention relates to novel cyclohexanediones having herbicidal activity, to agrochemical compositions containing those cyclohexanediones, to the use thereof for controlling undesired plant growth and to processes for the preparation of the compounds of the invention.
**to oo* The invention also relates to novel intermediates and to processes for the preparation thereof.
r Numerous substituted cyclohexane-1,3-diones having herbicidal activity are already known. These compounds are not always satisfactory in terms of strength of activity, duration of activity, selectivity and applicability. It has surprisingly been found that, in contrast to these known compounds, the novel cyclohexane-1,3-diones of the general formula I and I’ have good herbicidal activity.

t In the C-acylation according to process variant a) it has proved S advantageous to carry out the reaction in the presence of small amounts of cyanide, A low cyanide concentration can be ensured, for example, by the addition of acetone cyanohydrin.
c The rearrangement of the esters IV and IV’ can also advantageously be .o carried out under the action of cyanide ions and in the presence of a base.
Although the synthesis of the compounds of formula Ia and Ia’ outlined as reaction a) describes a process by which in principle a.l compounds included within the scope of formula la and Ia’ can be produced, for I reasons concerning economy and industrial scale production it may be appropriate to convert certain compounds of formula la and lI’ into other A ^derivatives included within the scope of formula I and Examples of such conversions, apart from reaction c) and are, for example, processes in which R 6 represents an ester, halogen or cyano radical.
These radicals can be converted analogously to the reactions illustrated hereinafter in Scheme 1 (IIa -4 IIb, IIc or IId) also even at the stage of compounds of formila I. Such derivatisation reactions are familiar to the person skilled in the art.
4 l;i 1 i 12 The above reactions are advantageously carried out in a solvent that is inert with respect to the reactions. Suitable inert solvents are hydrocarbons, such as benzene, toluene or xylene; ethers, such as diethyl ether, methyl isopropyl ether, glyme, diglyme; cyclic ethers, such as tetrahydrofuran and dioxane; ketones, such as acetone, methyl ethyl ketone; amides, such as dimethylformamide, N-methylpyrrolidone; sulfoxides, such as dimethyl sulfoxide; or chlorinated hydrocarbons, such as dichloromethane, trichloromethane, tetrachloromethane or tetrachloroethane, alcohols, such as methanol, ethanol, isopropanol, propanol, butanol etc..
t In some cases it is also advantageous to use mixtures of solvents in the i as form of organic solvents in admixture with water.
4 4 t The reaction temperature can be varied within wide limits. Suitable reaction temperatures raige, for example, from -20°C to the reflux temperature of the reaction mixture. The reaction is preferably carried out at a temperature of from 0 C to 100 0
C.
In the case of reactions a) and b) a base is advantageously added.
S Suitable bases are, inter alia, sodium, potassium and calcium hydroxide, alkali metal and alkaline earth metal carbonates, amines, such as, for S example triethylamine, or heterocycles, such as pyridine, 4-dimethylaminopyridine, DABCO and also alkali metal hydrides.
Reactions a) and b) can also advantageously be carried out under phase transfer conditions in two-phase systems. Such reactions are familiar to the person skilled in the art (for example described in Dehmlow and Dehmlow, Phase Transfer Catalysis, Verlag Chemie, Weinheim 1983; a” W.E. Keller, Phase Transfer Reactions Vol. 1 and Vol. 2, G. Thieme Verlag, Stuttgart 1986, 1987).

o 4 The invention also relates to a herbicidal composition for controlling undesired plant growth containing a compound of formula I 20 according to the invention together with further adjuvants and/or carriers.
The invention further relates to a process for the preparation of a 0 herbicidal composition according to the invention which comprises mixing a compound of formula I with the adjuvants and/or carriers.
The invention also relates to a method of controlling undesired plant growth at a locus, which method comprises treating the locus with a compound of formula I or a herbicidal composition according to the invention in a amount which effectively controls the undesired plant growth.
Another form of the invention relates to seeds when treated with a herbicidally effective amount of a compound of formula I or a herbicidal composition according to the invention.
The compounds of formula I are highly active ingredients for plants /336f 15A that at suitable rates of application are excellently suitable as selective herbicides for controlling weeds in crops of useful plants. That is to say, at such rates of application the active ingredients of formula I are distinguished by a good selective herbicidal property against weeds. In particular, cereals, such as rye, barley, oats, wheat and maize, but also other crop planes, such as sorghum, rice, cotton, sugar cane or soybeans or also permanent crops (such as, for example, vines or plantations) remain virtually undamaged at low rates of application. At increased rates of application the growth of the crop plants is influenced only to a small extent. If the rates of application are r 4 I 4 f r a I t ts C o t t a-
B^
r. 16 very high, the substances of formula I have total herbicidal properties.
The rates of application are generally from 0.001 to 4 kg, preferably from 0.005 to 2 kg of active substance per hectare.
At high rates of application the compounds of formula I can also be used as total herbicides. They are especially suitable for controlling weeds on paths, in public areas, on railway tracks or in other areas in which a total kill of the plants growing there is desired.
The selective herbicidal activity of the compounds of the invention is observed both in pre-emergence and post-emergence application. These compounds can therefore be used with equal success pre- or post-emergence in selective weed control.
,Advantageously, the compounds or compositions of the invention can be applied also to the propagation material of the crop plant. Seed cressi ,i ing, especially, may be mentioned here. Propagation material is seeds, o plantlets or other parts of the plant from which the crop plants can be reared. The invention also relates to the propagation material treated with an effective amount of a compound of formula I.
.oo The invention relates also to herbicidal compositions that contain a novel compound of formula I, and to methods for pre-and post-emergence weed control.
e The compounds of formula I are used in unmodified form or, preferably, in the form of compositions together with the adjuvants conventionally employed in the art of formulation, and are therefore formulateA in knovn manner e.g. into emulsifiable concentrates, directly sprayable or S dilutable solutions, dilute emulsions, wettable powders, soluble powders, dusts, granulates, and also encapsulations in e.g. polymer substances. As with the nature of the compositions, the methods of application, such as spraying, atomising, dusting, scattering or pouring, are chosen in accordance with the intended objectives and the prevailing circumstances.
i A 17 The formulations, i.e. the compositions, preparations or mixtures containing the compound (active ingredient) of formula I and, where appropriate, a solid or liquid adjuvant or extender, are prepared in known manner, e.g. by homogeneously mixing and/or grinding the active ingredients with extenders, e.g. solvents, solid carriers and, where appropriate, surface-active compounds (surfactants).
Suitable solvents or extenders are: aromatic hydrocarbons, preferably the fractions containing 8 to 12 carbon atoms, e.g. xylene mixtures or substituted naphthalenes, phthalates such as dibutyl phthalate or dioctyl phthalate, aliphatic hydrocarbons such as cyclohexane or paraffins, alcohols and glycols and their ethers and esters, such as ethanol, ethylene glycol, othylene glycol monomethyl or monoethyl ether, ketones S such as cyclohexanone, strongly polar solvents such as N-methyl-2-pyrroj lidone, dimethyl sulfoxide or dimethylformamide, as well as vegetable ;j oils or epoxidised vegetable oils, such as epoxidised coconut oil or soybean oil; or water.
The solid carriers used e.g. for dusts and dispersible powders are normally natural mineral fillers such as calcite, talcum, kaolin, montmorillonite or attapulgite. In order to improve the physical proper- Sties it is also possible to add highly dispersed silicic acid or highly S dispersed absorbent polymers. Suitable granulated adsorptive carriers are porous types, for example pumice, broken brick, sepiolite or bentonite; S and suitable nonsorbent carriers are, for example, calcite or sand. In addition, a great number of pregranulated materials of inorganic or organic nature can be used, e.g. especially dolomite or pulverised plant residues.
Depending on the nature of the compound of formula I to be formulated, suitable surface-active compounds are non-ionic, cationic and/or anionic surfactants having good emulsifying, dispersing and wetting properties.
The term “surfactants” will also be understood as comprising mixtures of surfactants.
Both so-called water-soluble soaps and also water-soluble synthetic surface-active compounds are suitable anionic surfactants.
18 Suitable soaps are the alkali metal salts, alkaline earth metal salts or unsubstituted or substituted ammonium salts of higher fatty acids (C 0’22), e.g. the sodium or potassium salts of oleic or stearic acid or of natural fatty acid mixtures which can be obtained e.g. from coconut oil or tallow oil. Mention may also be made of fatty acid methyltaurin salts.
More frequently, however, so-called synthetic surfactants are used, especially fatty sulfonates, fatty sulfates, sulfonated benzimidazole derivatives or alkylarylsulfonates.
The fatty sulfonates or sulfates are usually in th form of alkali metal S salts, alkaline earth metal salts or unsubstituted or substituted ammonium salts and contain a Cs-Czzalkyl radical which also includes the alkyl moiety of acyl radicals, e.g. the sodium or calcium salt of Slignosulfonic acid, of dodecylsulfate or of a mixture of fatty alcohol V, sulfates obtained from natural fatty acids.
These compounds also comprise the salts of sulfated and sulfonated fatty alcohol/ethylene oxide adducts. The sulfonated benzimidazole derivatives preferably contain 2 sulfonic acid groups and one fatty acid radical containing 8 to 22 carbon atoms. Examples of alkylarylsulfonates are the sodium, calcium or triethanolamine salts of dodecylbenzenesulfonic acid, dibutylnaphthalenesulfonic acid, or of a condensate of naphthalene- S sulfonic acid and formaldehyde.
Also suitable are corresponding phosphates, e.g. salts of the phosphoric acid ester of an adduct of p-nonylphenol with 4 to 14 moles of ethylene oxide, or phospholipids.
Non-ionic surfactants are preferably polyglycol ether derivatives of aliphatic or cycloaliphati: alcohols, saturated or unsaturated fatty acids and alkylphenols, said derivatives containing 3 to 10 glycol ether groups and 8 to 20 carbon atoms in the (aliphatic) hydrocarbon moiety and 6 to 18 carbon atoms in the alkyl moiety of the alkylphenols.
I.
?Li 1 1 r. atoms ir Lt.e alkyl chain, which adducts contain 20 to 250 ethylene glycol ether groups and 10 to 100 propylene glycol ether groups. These compounds usually contain 1 to 5 ethylene glycol units per propylene glycol unit.
Examples of non-ionic surfactants are nonylphenolpolyethoxyethanols, castor oil polyglycol ethers, polypropylene/polyethylene oxide adducts, tributylphenoxypolyethoxyethanol, polyethylene glycol and octylphenoxypolyethoxyethanol.
Fatty acid esters of polyoxyethylene sorbitan, e.g. polyoxyethylene St f ,I 1 sorbitan trioleate, are also suitable non-ionic surfactants.
Cationic surfactants are preferably quaternary ammonium salts which S contain, as N-substituent, at least one CB-C 22 alkyl radical and, as f t further substituents, unsubstituted or halogenated lower alkyl, benzyl or S hydroxy-lower alkyl radicals. The salts are preferably in the form of halides, methylsulfates or ethylsulfates, e.g. stearyltrimethylammonium chloride or benzyldi(2-chloroethyl)ethylammonium bromide.
I t V S Surfactants customary in the art of formulation are described, inter alia, in the following publications: “1986 International Mc Cutcheon’s Emulsifiers and Detcrgents”, Glen Rock, USA, 1986; H. Stache “Tensid Taschenbuch”, 2nd edition, C. Hanser Verlag, Munich/Vienna, 1981; M. and J. Ash. “Encyclopedia of Surfactants”, Vol. I-III, Chemical Publishing Co., New York, 1980-1981.
The active ingredient preparations usually contain 0.1 to 95 preferably 0.1 to 80 of a compound of formula I, 1 to 99.9 of one or more solid or liquid adjuvants, and 0 to 25 of a surfactant.
Preferred formulations are composed especially as follows (throughout, percentages are by weight)

t B. Biological Examples i Example Bl: Pre-emergence herbicidal action t In a greenhouse, immediately after sowing the test plants in seed trays the surface of the soil is treated with an aqueous dispersion of the test compound obtained from a 25 emulsifiable concentrate. Various rates of application of active ingredient/hectare are tested. The seed trays are kept in the greenhouse at 22-25 0 C and 50-70 relative humidity and the test is evaluated after 3 weeks.
The herbicidal action is assessed in comparison with an untreated control group using a nine-stage evaluation scale (1 total damage of the test plants, 9 no herbicidal actic, on the test plants).
~I_
67 Ratings of 1 to 4 (especially 1 to 3) indicate a good to very good herbicidal action. Ratings of 6 to 9 (especially 7 to 9) indicate a good tolerance (especially in the case of crop plants). The test results for compound No. 1.005 are compiled in Table 4.

After sowing, the beakers are filled to the soil surface with water. 3 days after sowing, the water level is raised to slightly above (3-5 mm) the surface of the soil. Application is carried out 3 days after sowing by spraying an aqueous emulsion of the test substances onto the vessels at a rate of Sapplication of 60 to 250 g of active ingredient per hectare. The plant beakers are then placed in a greenhouse under optimum growth conditions for the rice weeds, i.e. at 25 0 -30 0 C and high humidity. The tests are evaluated 3 weeks after the application. The compounds of Table 1 damage the weeds but not the rice.
